LOUIS AUGUST SENGELE, OF VICTORIA, TEXAS, ASSIGNOR 0F ONE-THIRD TO LACYT. STEELE, OF VICTGRIA, TEXAS.

POT-FEEDER FOR TYPE-CASTING MACHINES.

To all whom "it may concern:

Be it known that I, LOUIS AUGUST SEN- onnn, a citizen of the UnitedStates, and a resident of Victoria, in the COllllly of Victoria andState of Texas, have invented anew and Improved Pot-Feeder for TypeCasting Machines, of which the following is a full, clear, and exactdescription.

My invention relates to type-setting and type-casting machines, and moreparticularly to such machines as are employed to cast slugs providedwith impression characters, each slug representing the line, or itsequivalent, to be printed.

The main purposes of my invention are as follows: 1. To produce for acasting machine, in which there is a metal pot containing the type metalto be cast up into slugs, a

device provided with means for dropping into the metal pot old anduseless slugs, one at a time, as the molten metal in the metal pot isused up in making new slugs. 2. To render the pot feeder adjustable forslugs of different len ths. 3. To prevent breakage of any movable part,due to difficulty in ejecting slug. In this connection it may not beamiss to state one or two facts concerning the operation of castingmachines of the general type above mentioned.

To obtain the best results it is absolutely.

requisite that the metal in the metal-pot should be kept at an eventemperature, neither too hot nor too cool. It is also essential that themolten metal in the pot be maintained at a. certain height. If thetemperature of the metal is too high, it will cause hollow slugs, andwill also cause the slugs to adhere to the mold. Too hot metal will alsosoon break down the matrices. If, on the other hand, the temperature istoo low, the plunger cannot force the metal into the mold properly,causing a bad and useless slug. If the metal gets low in the pot it willalso cause ill results. Ordinarily, the operator feeds the metal in thepot by hand, which necessitates his loaving the keyboard, causing lossof time and inconvenience during the day. If too much metal is added towhat is in the metal-pot, such fresh metal being cool will lower thetemperature of the molten metal. The regularity with which the gain andloss is equalized by this contrivance, both as to quantity and time,proves its capability of maintaining, not only a regular supply of metalbut a uni- Specification of Letters Patent.

formity of temperature of the molten metal. Operators sometimes forgetto put metal in the pot at the required time, which produces the illeffects of low metal. By my pot-feeder all these disadvantages areovercome, enabling the operator to remain at the keyboard, therebygreatly increasing the output of the machine. My invention seeks,therefore, upon each occasion when a supply of metal is forced out ofthe metal pot for the purpose of casting a slug, to add to the metalinside of the metal pot a quantity of cold metal, equal to that ejectedfor the purpose of casting a new slug. As a convenient means for doingthis I simply cause the old slugs, which have already been used, to befed one at a time into the metal pot, substantially the same movement ofmechanism used for forcing out a charge of metal sufficient to fill theslug mold, sufficing also to drop into the metal pot an old slug or anequivalent quantity of cold metal. By this arrangement I replenish themetal contained in the metal pot as fast as it is used, therebymaintaining approximately constant the quantity contained in the metalpot, and also maintaining the temperature of the metal pot and itscontents as nearly as practicable uniform.

Reference is to be had to the acconipanying drawings forming a partofthis specifi ation, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a. fragmentary elevation show ing my device as applied to" aso-called linotype machine, this View showing the melting pot, a galleymounted thereover and extending upwardly therefrom for the purpose ofretaining the old slugs to be used in the replenishing of the'meltingpot; the view further showing lever mechanism connected with the liftingarm of the elevator for the purpose of enabling the movements of thisarm to actuate my improved mechanisn'i; Fig. 2 is a fragmentary viewpartly in eleva- 'tion and partly in section, showing the mechanismappearing in Fig. 1, but viewed as from the right of Fig. 1; Fig. 3 is afragmentary view partly in side elevation and partly in verticalsection, showing the galley containing the slugs to be melted, and showsthe ejecting blade and bell crank lever for actuating said plate inorder to eject. the slugs one at a time from the galley and into themetal pot; Fig. 1 is an elevation showing the galley and the ejectingmechanism for handling the slugs to be melted; Fig. 5 is a horizontalsection upon the line of Fig. 3, looking in the direction of the arrow,and showing how the ejector plate is operated by aid of a bell cranklever for the purpose of ejecting the slugs; Fig. (3 is a fragmentaryelevation somewhat similar to Fig. l, but showing the device operated inconnection with a comparatively wide galley and wide ejector plate, forthe purpose of operating upon slugs of greater length than those appearing in Figs. 1 to inclusive; Fig. 7 is a horizontal section upon theline 77 of Fig. 3, looking in the direction of the arrow, and showinghow the potfeeder is adjusted for slugs of different lengths; Fig. 8 isa fragmentary vertical section through the galley containing the slugsto be melted; and Fig. 9 is a detail showing how certain movable partsare automatically disconnected in order to prevent breakage in case aslug becomes fastened and is not easily dislodged from the galley.

At 7 is a galley having generally the form of a tall box. The galley isprovided with a door 8 connected with it by hinges 9 and provided withfastenings 10 whereby it may be temporarily secured in closed position.it 11 are shown the slugs which are to be melted up. The galley isremovable and is provided at its bottom with a slug stay 12 of the formshown in Fig. 6. This slug stay is simply a plate having a curved handle13 and extending through slots 1%, 15 so as to support the slugs 11.When the galley is otf the machine the slug stay prevents the slug fromdropping out of the bottom of the galley. When the galley is placedwithin the machine the operator grasps the handle 13 and withdraws theslug stay.

The door 8 and the back of the galley 7 are provided with peep holes 16,17 to enable the operator to see the slugs in the galley and thusascertain when the galley needs replenishing. A pair of angle strips 18are fitted with metallic ways 19 (see Figs. 3, t), and connected withthese ways are clips 20 bent toward each other, as will be understood.from Fig. 5. These clips are provided with inwardly extending bearingarms 21. L-shaped brackets 22 are connected with the clips 20 by aid ofbolts 23.

At 24: is shown an ejector plate which fits slidably into the ways 19and is adapted to reciprocate.

The ejector plate 24 is provided with a projecting portion 25 carrying apin 26. A bearing 27 of substantially U-shape fits over this pin and iscarried upon the lower end of an arm 28. This arm is journaled upon apivot rod 29 and is integral with an arm 30. The arms'28. 30 may beconsidered as a bell crank lever. As this lever rocks upon the pivot rod29, the ejector plate 24 reciprocates in a horizontal plane, ejectingthe slugs 11, one at a time, simply pushing them out dgewise, the lowerend of the galley being adjusted far enough above the angle strips 18for this purpose. These slugs drop through an opening 31 into the metalpot 32 and are melted up.

Brackets 33 are mounted upon the clips 20 and are provided with portions34 extending hcrizoptally therefrom. Bolts 35 extend upwardly throughthese portions. Brackets 36 are mounted upon opposite sides of thegalley and engage the bolts 35, the weight of the galley thus restingupon these bolts. The hei ht of the galley above the angle strips isthus controllable by aid of the bolts 35, and ditferent thicknesses ofslugs thus allowed for, as desired. hen the operator wishes to changethe thickness of the slugs, he turns the screw bolts As shown in Fig. 6,the device may be employed in connection with wider galleys, so as toaccon'unodate slugs of greater length. In Fig. 6 the galley is shown at'7, and except as to width is exactly like the galley 7 shown in otherviews. The pivot rod 29 provided with set collars 29 held rigidly butdetachably in position by aid of set screws 29. In order to substitutethe galley 7* for the galley 7, the latter lifted out and the galley 7put in place as shown in Fig. This is easily done by moving the anglestrips 18 farther apart, as hereinafter described, setting the collars2S) in new positions and replacing the ejector plate 24. with a widerejector plate 2 1. The arm 30 is journaled to a rod 37. The angle strips18 support the weight off the melting pot and brackets 18 are securedupon these angle strips by aid of fastenings 18". These brackets)artially encircle stationary arm 18 mounted upon the framework.

Tt will be noted that the pivot rod 29 is of sufficient length to extenda little distance through the bearing arms 21 so as to permit the readyadjustment of the collars 25 1 where longer slugs are to be used. It.will also be noted that the ejector plates 24L are easily removed andother plates 2t substituted for them, as will be understood from Fig. 3.The bearing 27 is easily raised oft the pin 26 by lifting the arm 30 asutlicient distance upward. The upper end of the rod 37 is provided witha slot 38 extending obliquely downward as indicated in Fig. 9. The rod37 is also provided at its upper end with a leaf spring 38 bent slightlyout "ard from the rod J and normally closing the outer opening of theslot 38. The arm 30 carries a pin 38" which is adapted to slip into theslot 38 by pressing the upper end of the spring 38 slightly away fromthe upper end of the rod 237. This rod is further provided with arounded or beveled surface 38, the

curvature of this surface mating approximately the cnrvz-itnre of theupper end of the l af spring 38.

The purpose of the arrangement shown in Fig. 9 is to enable the rod 37,upon being awn downnuirdly, to extricate itself from i re arm 30, if forany reason it should hap' pen that this arm is momentarily unable to 1form its stroke downward. For instance, i a s ug should happen to beunusually hard o move from the galley, there might be dauof breakingsome movable part, unless the part in question or some other part werefree to make its complete movement. As

37 is at all times free to move downwardly, v-ihethcr it can carry withit the arm 30 or not. it will also be seen that the connecion may bereadily restored between the rod -37 and the arm 30 by merely forcingthe rod 3? upward and guiding the curved surface 32% of the curved upperend of the leaf spring 3c in such manner that the pin forces the spring88 slightly away from the up'ier end of the rod 87 and enters he slot38. The machine therefore automatically pr from breakage in caseanything goes wrong with the ejecting of the slugs from the galley.

The lower end of the rod 37 is connected to a lever by aid of a pivotpin 40. The lever 39 is journaled upon a pedestal 42 and provided with anumber of holes 4C1 where- 't may be adjusted relatively to this ped-The pedestal is secured by a bolt 43 the floor 24. Journaled to thelever 39 d extending upwardly therefrom is a rod and a clamp 4:45 ismounted upon the upend of this rod, being secured thereto by of a pivotpin 47.

A clamping screw 4L8 secures the clamp at? upon the arn ll), this armbeing connected with a plunger used for operating the first elevator atthe machine, this plunger being connected by pivot pin 51 with the arm4C9. upon rocking shaft of tubular form, this rocking shaft beingsupported upon the framework 53.

Extending upwardly from the shaft 52 is an arm A. lever is, by aid of apivot pin so, journaled upon this arm 54 and is connected with the arm49. The upper end of the lever is provided with a roller 58 and thelatter is engaged by a revolnble cam 59 j ournaled upon the main shaft59 of the machine. The mold wheel is shown at 0, and a bearing (31,mounted upon the stationary arm 18, supports the vise mechanism.

The operation of my device is as follows: The galley T is removed fromthe machine and tilled, or partially filled, with slugs 11 to be meltedup. The slug stay 12 prevents the slugs from dropping out while thegalley miv be seen from Fig. however, the rod The arm at?) is mountedrigidly is being handled. The galley having been replaced in the machinethe slug stay is removed. ris different thicknesses of slugs may beemployed, the bolts are adjusted every time the device is used inconnection with slugs of different thicknesses. The lever 39 may also beadjusted relatively to the pedestal l2, and the rod 37 may be adjustedrelatively to the arm 30 whenever de sired. Power being applied to themain shaft 59 the cam turns, and by acting upon the roller 58 causes thelever F5 to rock. This causes the arm l-t) to rock and the plunger 50(for the first elevator) is thus caused to reciprocate vertically Thearm acting through the rod il-5, causes the lever 39 to oscillate, andthis lever, acting through the rod 3?, actuates the arm 30. The lattercauses the ejector plate 24. to reciprocate so as to eject the slugs 11one at a time throu h the opening 31 in the melting pct 32. The meltingpot is thus periodically relieved of small charges of molten metal, andas ea h charge of metal is ejected the contents of the me al pot arereplenished by the entrance of a single. slug.
